ABSTRACT

Hydraulic networks are considered, which are characterized by a significant influence of pressure (potential) losses on nodal elements that are tees or are represented by them so that the degree of nodes of the design graph does not exceed 3. The RV algorithm is proposed for the automatic formation of a set of defining nodes, each of which, when broken, ensures the break of two cycles of the system of fundamental cycles of the graph, built on the basis of the system of chords obtained by the method of searching in width when constructing the spanning tree. The RV algorithm proposed for selecting the defining nodes does not break the graph’s connectivity. And in cases where cycles remain after the breaks of the defining nodes, such cycles will be isolated.

KEYWORDS
